I want to create a textfield using react mui textfield. But when I add the multiline prop it gives two boxes with border. how to remove the inner box margin
I tried several css and styling options but didn't work
The issue you're encountering is likely due to the default styling of the TextField component in Material-UI.
One solution to remove the inner margin of the TextField is to use the sx prop to override the default styles.
Documentation on how to use sx prop: https://mui.com/system/getting-started/the-sx-prop/
Example below:
<TextField
multiline
sx={{ p: 0, m: 0 }}
/>

I m currently using the slider from react-native-community and i am having trouble doing more than one thing while using onValueChange.
now the value taken from onValueChange is set to control the strokeDashOffset (sdo) of an SVG element. It is working just fine but i need to add some more rendering depending on the slider value. That's to say for example when the value reaches 340 i need to setState something, then when it reaches 650 i need to set some other state etc...
here is the code of my slider :
<Slider style={styles.slider}
minimumValue={0}
maximumValue={1570}
value={sdo}
step={1}
onValueChange = {value => setSdo(value)}
/>
(in my svg component the strokeDashOffset is set to this sdo value but i don't feel like putting my svg code is relevant here, I guess i have to add some stuff in the onValueChange but i cannot use if statements and i have no idea how to proceed)
How can i conditionally render things based on the slider value (while stille having the slider value attached to strokeDashOffset of my SVG)?
thanks in advance !
I currently have a modal where the user can pick from a large flatlist of icons. All have size: '45' and color: 'white'. When a user selects an icon, the modal is closed and their selected icon appears on the card (this feature is one that allows the user to create a custom card).
I then have a feature that allows the user to change the line colour from white to black and visa versa on the card to contrast with their selected background colour. I would also like the colour of the icon to change with the lines, but I cannot find a solution! The icon object itself is read-only and using a StyleSheet seems to only apply styles when it is referenced within the original call like:
<FontAwesomeIcon icon={archive} style = {styles.text} />
I can't seem to wrap it in a styled view and then change the style from there.
Any ideas on how to alter the colour? And the size while I'm asking?
You can make state like this :
const [style,setStyle]=useState()
You change state with user color, and apply it to your FontAwesome icon
<FontAwesomeIcon icon={archive} style = {style} />
Thanks for the answers! I ended up creating a library to reference and just passed the library prefix (fab, far, fas) and the icon name (coffee, archive, wifi). Then used:
<FontAwesomeIcon icon={[icon.props.icon[0], icon.props.icon[1]]} style ={blabla} size = {blabla} />
Meaning I can now manipulate the size and colour wherever I want! Very handy.
as the doc says: ellipsizemode props defines how text will be truncated. in my case, i want to show a expand button instead of ellipsis glyph, and i could expand the text to show all of them by press the button.
so i want to figure out how numberOfLines actually works in Text component in react-native. then i could archive this, anyone could help?
It will show your content in <Text> component which is fitted in those numberOfLines.
With output you are expecting or want to perform, you can use dynamic numberOfLines using state.
Just have that state variable default value of lineNumbers and change it when pressing on button or any other component.
this.state = {
lineNumbers: 2
}
This indicates your numberOfLines will be default 2, and once user press on button or read more
this.setState({lineNumbers: null})
It will show whole content.
<Text numberOfLines={this.state.lineNumbers}>
I need to align this long text and it should start from left. As shown in the following image the end of the text is nicely displayed and start is hidden.
How to start the text from left,
alignText: 'left'
didnt work.
Geocoder.geocodePosition({
lat: origin.latitude,
lng: origin.longitude
}).then(res => {
console.log(res[0]);
this._destination.setAddressText(res[0].formattedAddress);
});
Here the formattedAddress is very long, I need to show it from the begining.
By default this is working in iOS.
try maxLength. assign value for maxlength according to visible text size. Otherwise use multiline=true if you want to show the full text.
ex:
<TextInput maxLength={50} />

https://reactnative.dev/docs/textinput.html#maxlength
https://reactnative.dev/docs/textinput.html#multiline
You need to learn about flex box system in react native :
flexDirection : 'row' -> used to set the text in row direction.
alignSelf : 'flex-start' -> used to set the start from the left.
Also please read it from there React Native Basics flexbox
I am using Tcomb Form Native for forms and putting auto tag for placeholder in the options. However I would like to change the style for the text displayed. Is it possible to change that ?
var options = {
auto: 'placeholders',
};
<TextInput/> takes a prop of placeholderTextColor additionally the placeholder text should inherit whatever styles you put on the TextInput see the following example here: https://rnplay.org/apps/Yyfuag
